What the hell are you talking about? Who are you talking to?

You don't need a ‘framework’ to write JavaScript. And HTML doesn't ‘simulate’ a GUI, it in fact provides a paradigm and an engine ready for rendering gobs of text, images and whatnot, on which any other typical GUI framework would choke like a little baby. And you would have to implement any minuscule element from scratch in godforsaken C++ of all things.

Maybe learn a thing or two of what you're trying to speak about.
